This is the one for people only wanting 0NE amp in their vehicle. It runs 2 pairs of MB QUART REFERENCE 6 3/4" components, and one ALPINE TYPE R 10'sub. All of this is in a 97 YUKON and sounds great. CLEAN POWER. When people find out 1 amp is running my system......jaws drop!

sounds great. mine overheated and cut-out a few times so i had to move it to an area with better air flow... once i did that, no problems at all. this amp is clean and loud. i have the sub channel wired to a dual coil alpine 12" series R, 2ohm. waaaaay more bass than i need.

I have to give this Alpine F450 really great marks, if you short on space and you need a powerful quality amp you can' t beat this unit for the money. This amp is just behind amps like the JL Audio 500/5, but they are almost twice the money. This amp is a one of the best bang for the buck multi-channels on the market.
